My Trip to Beijing

<正>I took a trip to Beijing with my parents during the seven-day holiday.We all had a happy time.On the first day,we went to the Wangfujing Street.It’s a busy shopping street.We went into many stores.I didn’t buy any clothes but bought two books in the Wangfujing Bookstore.On the second day,we climbed the Great Wall.The wall looks like the tail of a huge dragon.While I was climbing,I thought of the saying"One who fails to reach the Great Wall is not a hero."Later in     

A Wonderful Trip

<正>Dear Jack,How is it going?Last summer vacation, I went to Beijing, China with my parents. On the first day, we visited the Great Wall. It was very long and tall! Climbed~①it made me tired but excited. On the second day, we went to the Palace Museum. I was surprised to see so many wonderful things~②. On the third day, we tried some Chinese food in a small restaurant. It was a pity that I couldn’t use chopsticks~③. On the last day, we went shopping in a big supermarket near     

Travel to the Great Wall

<正>We’ll travel to Beijing this summer vacation and we will visit the Great Wall first.It is a symbol of our country and one of the New Seven Wonders of the world,too.It’s 75km away from the center of Beijing.It’s about6,700 kilometers long.In most places on the Great Wall,it’s wide enough for 5 horses and ten men to walk side by side.Every year many foreigners come to visit it.When they see the Great Wall,they always     

北京长城文化带线性遗产体系构建与类型 研究

在长城国家文化公园及北京长城文化带建设背景下, 对北京长城线性遗产体系开展研究具有重要理论和现实意义。 长城作为一种独特的线性遗产,周围环境险峻,是不可通达 的。而目前关于长城风景道规划是以定性研判为主,亟须探索 数据驱动的计算型方法,以整合长城沿线数量众多、类型多样 的数据资源,形成定量、综合的线性遗产体系构建方法。以北 京长城文化带为研究范围,利用ArcGIS空间分析技术,采取最 小累积阻力模型(MCR)与多中心性评价模型(MCA)构建长城 线性文化遗产体系并进行测度、分级,借助核密度估计法和典 型案例分析来揭示其空间结构与类型特征,从而构建北京长城 文化带线性遗产体系。通过展示基于空间数据挖掘技术的线性 遗产体系构建与分级分类方法,拓展了中国线性遗产体系的概 念外延和研究类型,从而精细刻画线性遗产的空间等级与功能 性质,对风景线路体系规划、旅游服务设施配置、线路主题划 定及展示利用策划具有参考价值。     

Sustainability evaluation of the Great Wall of China using fuzzy set concepts by incorporating Leadership Energy and Environmental Design

This paper discusses the sustainability performance of the ancient construction method and the service life during the Ming Dynasty on the Great Wall of China in Jinshanling. Jinshanling section of the Great Wall is located in Luanping County, approximately 150?km northeast of Beijing, China [“Beijing China to Jinshanling China.” 2015. Google Maps, October 10. Accessed October 10, 2015]. To determine whether the Great Wall was sustainable during the time period, i.e. the Ming Dynasty, the authors use Leadership in Energy and Environmental Design guide and fuzzy set concepts (with the centroid method). The results of these methodologies demonstrate that the Great Wall of China in Jinshanling was fairly sustainable during the Ming Dynasty. After the conclusion of this paper, the authors hope to open up further research on whether the ancient construction methods from the Great Wall of China can be sustainable and used in today’s construction industry.     

My Summer Vacation

<正>Hello,everybody!I’d like to tell you something about my summer vacation.This summer I went to Beijing with my parents.The weather there was very fine but a little hot.We visited many places of interest,such as the Palace Museum,the Great Wall,Tian’anmen Square,but I like the Summer Palace best.It is so great.Many people from different countries come to visit it every year.I really had a good time there.Could you tell me something about your vacation?     

长城文化景观研究的方法探索与框架构建

长城国家文化公园建设既是国家文化战略,也是区域发展战略。借助文化景观理论,可将人群、文化、历史、地理和环境等诸多与长城有密切关系却常被忽视的要素纳入到同一“区域”空间下进行整体考察,有助于长城遗产价值的系统阐释和区域的可持续发展。然而,目前关于文化景观的研究多偏向于应用研究,在方法论层面的研究和探讨仅有为数不多的国外学者。长城作为超大尺度的文化景观,具有突 出的“历史复杂性”,构建一个多维度的长城文化景观研究框架十分必要。通过梳理国外文化景观的研究方法、框架和模型,结合长城自身特点,提出以人类活动、文化传统、景观形态 3 个要素为核心,以时间与空间为轴,构建长城文化景观的研究框架。在北京长城文化景观的研究中,使用此研究框架有助于探寻其形成、发展和变迁的机制与驱动力,对于区域规划具有重要指导意义。     

基于长城保护性修缮的遗址顶面植物处置 技术体系基础研究

长城是国家重点保护文物及世界文化遗产。长城遗 产的保护性修缮以修复长城既有建筑病害、根除结构安全隐患 的过程“最低限度干预”但同时“原状保护”为目标。北京长 城遗址顶面植物是导致长城建筑病害发生且持续恶化的因素之 一,但若大规模无差别清除则可能危害长城遗产本体,因而针 对如何科学处置长城遗址顶面植物尚存在学术争议。以北京大 庄科长城保护性修缮工程实践为例,前期已实地调研完成并阐 明长城遗址顶面植物种类及空间分布特征,在此基础上分析由 其导致的长城建筑病害类型及其结构破坏机理;依据前期已阐 明长城遗址顶面植物定量化评价体系及植物处置原则,进一步 阐述长城遗址顶面植物地上部分清除后残存根系的处置技术体 系,以及利用长城遗址顶面原堆积土及保留植物、分层回填因 修缮剥离的原堆积土及其种子库再生植物形成“软盖层”保护 体系。研究成果为修复长城建筑病害、修缮后在长城遗址顶面 实施“软盖层”保护提供基础科学依据。

金长城军事防御体系概述

很长时间以来,金长城被排斥在＂长城＂范围之外。这一方面说明学界对＂金长城＂防御体系认识不足,另一方面也说明金长城与其他长城有明显区别。金长城军事防御体系是在汉文化的熏陶下形成的,但其规划特点和建筑形式却带有明显的游牧民族文化特质。通过深入的探讨,真实地还原其构筑初衷,为金长城遗址的保护工作提供理论支持。
